Open Source Pumpkin PCB

Eric over at Low Voltage Labs has posted up his design for a simple PCB ideal for putting an LED into a pumpkin. This is very much like our simple LED pumpkin project but in a neat, reusable format. And it makes a mighty cute little jack-o-lantern all on its own.

He has made it available as a kit with PCB, switch, resistor, battery holder and the same candle flicker LEDs which we love so much. Unfortunately, the kit is currently sold out. Hopefully he’ll make more, if not in time for this Halloween, then at least for next year.

Well jeez. If you’re going to go to the trouble of printing a board, you might as well make it a joule thief. Or put a timer on it, for when you put it on your porch and forget to turn it off. Or *something*…

Thanks Lenore. The pumpkin PCB was actually inspired by your Simple LED pumpkins. I bought some of the flickering LEDs from your store last year for myself and a friend. My friend asked me to make a circuit board with a switch so he didn’t have un-tape the LED every night. :)

We are sold out for this year, but check back next year for more stock and a new version of the PCB.

CR2032′s aren’t hard to find if you shop at the right places, but point taken.

A 9 V is actually a rather inefficient battery– with a lot of internal structure –for times when you really need 9 V. By comparison, it’s extremely efficient to run from two AA cells, or even two AAA cells, if you want 3 V.
